Caution
•
Be sure to wire correctly and securely.
Failure to observe this caution may result in electric actuators overrun, injury, or malfunction.
•
Do not connect a commercial power supply to the U, V, or W terminals for the motor cable connection.
Failure to observe this caution may result in injury or fire.
•
Securely connect the main circuit terminals.
Failure to observe this caution may result in fire.
•
Do not bundle or run the main circuit cables together with the I/O signal cables or the encoder cables in
the same duct. Keep the main circuit cables separated from the I/O signal cables and the encoder
cables with a gap of at least 30 cm.
Placing these cables too close to each other may result in malfunction.
•
Use shielded twisted-pair cables or screened unshielded twisted-pair cables for I/O signal cables and
the encoder cables.
•
The maximum wiring length is 3 m for I/O signal cables, 50 m for encoder cables or servomotor main
circuit cables.
•
Do not touch the power supply terminals while the CHARGE lamp is ON after turning power OFF
because high voltage may still remain in the DRIVER.
Make sure the charge indicator is OFF first before starting to do wiring or inspections.
•
Be sure to observe the following precautions when wiring the DRIVER main circuit terminal blocks.
• Do not turn the DRIVER power ON until all wiring, including the main circuit terminal blocks, has
been completed.
• Remove detachable main circuit terminals from the DRIVER prior to wiring.
• Insert only one power line per opening in the main circuit terminals.
• Make sure that no part of the core wire comes into contact with (i.e., short-circuits) adjacent wires.
•
Install a battery at either the host controller or the DRIVER, but not both.
It is dangerous to install batteries at both ends simultaneously, because that sets up a loop circuit
between the batteries.
•
Always use the specified power supply voltage.
An incorrect voltage may result in fire or malfunction.
•
Make sure that the polarity is correct.
Incorrect polarity may cause ruptures or damage.
•
Take appropriate measures to ensure that the input power supply is supplied within the specified
voltage fluctuation range. Be particularly careful in places where the power supply is unstable. An
incorrect power supply may result in damage to the equipment.
•
Install external breakers or other safety devices against short-circuiting in external wiring.
Failure to observe this caution may result in fire.
•
Take appropriate and sufficient countermeasures for each form of potential interference when
installing systems in the following locations.
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields and magnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power supplies
Failure to observe this caution may result in damage to the equipment.
•
Do not reverse the polarity of the battery when connecting it.
Failure to observe this caution may damage the battery, the DRIVER or electric actuaters, or cause an
explosion.
•
Wiring or inspection must be performed by a technical expert.
•
Use a 24-VDC power supply with double insulation or reinforced insulation.
